Farrnm'r LOUIS A. HOERR, OF ST. LOUIS, MISSOURI.

CARVTRUCK.

SPECIFICATION forming' part of Letters Patent No. 634,891., dated October 17, 1899. Application filed April 24, 1899. Serial No. '714,161Y (No model.)

T0 a/Z whom, Lr may concern:

Be it known that I, LOUIS A. HOERR, acitizen of the United States, residing at St. Louis, in the State of Missouri, have invented an lmprovement in Oar-'lrucks, of Which the following is a specication.

Myimprovement relates tothe ends of cartrucks; and the chief objects of myinvention are, first, to provide improved means for holding the arch-bars in position in case of the breakage of a column-bolt; second, to provide means for preventing the inverted-arch bars and tie-bars from becoming displaced when column-bolts break; third, to provide means for diminishing the strain upon the columnbolts and thus preventing them from breaking, and, fourth, to provide means for preventing arch-bars and inverted-arch bars from buckling, as they frequently do in the constructions now in use. Isecure these objects by the mechanism illustrated in the accompanying drawings, in Which- Figure l is a side elevation of a portion of a truck end embodying my improvement in its preferred form. Fig. 2 is a plan view of the same parts. Fig. 3 is a horizontal cross-section on the line 3 3, Fig. l. Fig. 4 is a vertical section on line 4 4, Fig. 2. Fig. 5 is a side elevation. Fig. 6 is a detailed vertical longitudinal section on line 6 6, Fig. 7. Fig. 7 is a detailed isometric projection of a pair of column-caps formed integral. Fig. Sis a detailed vertical section on line 8 8, Fig. 9. Fig. 9 isa detailed isometric projection of a column. Fig. lO is a vertical longitudinal section of a detail. Fig. ll is a centralvertical longitudinal section of a modification corresponding to Fig. 4, but with the bolster-springs omitted; and Fig. l2 is a detailed isometric projection of the forni of corner-cap shown in Fig. 11.

Similar letters referto similar parts throughout the several views.

A, Figs. l, 2, 3, 4, 5, and ll, represents an arch-bar, B an inverted-arch bar, and O a tierod, all of which are of common form.

D, Figs. l, 3, 4, 5, 7, and ll, represents truck-end columns. Each column D preferably has a pair of outwardly-projecting ears CZ at its upper end and a similar pair of ears The ears are pierced by fl at its lower end.

holes cl2 for the passage of keys or bolts cl3. The ends of the columns are preferably each closed by a web d", having an exterior bevel d5 along its outer edge, and each column contains a bolthole (Z6 for the passage of a column-bolt D. The columns are arranged opposite each other in the usual manner. In the form of truck end shown the lower ends are connected by a spring-seat E and bolts e passing through said seat and column-'flan ges all; but this form of connection is not essential, The spring-seat may be of any suitable form and may be forined'integral with the column-girders, if desired, as will be obvious.

F is the truck-bolster,and G bolster-springs.

The arch-bar A preferably rests directly upon the upper ends of the columns, Whose lower ends preferably rest upon the invertedarch bar B, and the tie-bar O may lie next the inverted-arch bar, as shown, though this is not essential. The arch-bars are held in place and connected with the columns by means of a pair of caps H, Which are preferably formed integral, as shown in Figs. l, 2, 4, G, and 7; but though I consider it best to form them integral they retain a large share oi' their value when made separate, as indica-ted in Figs. l1 and l2. Each cap is preferably com`v posed of a top 7i, containing a bolt-hole 7i and a pair of doWnwardly-projectin g ears h2, each pierced by a hole h3 for the passage of a key or bolt, andA said cap is preferably secured in place in part by the column-bolt D', passing through the hole 7i in its top h, and partly by a bolt or key d3, passing through the holes h3 in its ears h2 and the holes cl2 in the column-ears d. The cap preferably rests directly upon the arch-bar beneath, and its top 72, 'preferably inclines downward on the under side of its outer end h4, as shown most clearly in Figs. 4 and, so as to be substantially parallel with` the bevel d5 beneath in the top of the column. This formation of the inside of the cap and the corresponding form of the top of the column beneath enable the arch-bars to be clamped securely between the columns and caps at` the points where the bends in the arch-bar are located. They are the points at which such barshave heretofore buckled, and such buckling is eifectu ally prevented by my caps.

-for purposes of convenience.

The shearing strain upon the column-bolts is very great where truck ends are constructed according to the methods heretofore adopted, and this has frequently resulted in accidents. 'In the case of my improved truck end the capears h2 and the cap-keys or bolt d3 take alarge part of the strain heretofore borne by the column-bolts, and where the caps II are formed integral, as I prefer to make them, the caps and their keys cooperate directly in relieving the column-bolts from strain 'in a very advantageous manner. There they are not made integral, they still coperate togetherby reason of the transmission of strains from one to the other through the arch-bar, but the cooperation is not quite so perfect.

The inverted-arch bars, like the arch-bars, have heretofore buckled at the point-s where thebends are located. Said bends in the inverted-arch bar are lettered l), and in case of the breakage of a bolt both the arch-bar and the rods C are liable to become displaced. To prevent these difficulties, I preferably use a pair of inverted caps I', Figs. 1,4, 5, l0, and 1l, one for each column.

The caps I are preferably like the caps I-I in all their features and are given a different letter merely by reason of their positions and Like the caps Il, they are preferably formed integral, as shown in Figs. 1,14, and 10, but may be made separate, as indicated in Fig. ll.- Their bases t' are provided with column bolt-holes 1'/ and preferably turn up at the outer edge 2, so as to fit the bends in the part resting therein. In the form of truck end shown this part is the tie-bar C, whose bends c lie between the part t' of the cap and the bend c ofthe inverted-arch bar. Each cap I is provided with apair of upwardly-proj ectin g ears i3, provided with holes i4, through which a bolt or key passes, which also extends through the holes d2 in the ears d of a column.

In the form of truck end shown the upper ends of the columns are not connected by any part formed integral therewith and no such part is necessary. My caps H are very useful, however, no matter how the columns are connected, though they are most useful where the upper ends of the columns are connected substantially as shown. The caps I are also useful, whether the lower ends of the columns are connected by a separate part, as shown,

-or by a part formed integral therewith in the manner customary in many well-known forms.

Vhere in my claims I use the word cap,77 I desire to be understood as including inverted caps as well as those which are upright.

I claimf l. As a new article of manufacture, a re; movable column-cap having perforated ears for connecting it to a column, substantially as described.

2. As a new article' of manufacture, a removable columncap having a pair of perforated ears connected by a part formed to iit the outside of the bend in a bar or tie.

3. As a new article of manufacture, a pair of column-caps formed integral and separable from the columns, and each having a pair of ears for attachment to a column, substantially as described.

4. As a new article of manufacture, a pair of removable column-caps, formed integral and each having a pair of ears connected by a part formed to fit the outside of the bend in a bar or tie.

The combination in a truck end of a column having a lateral perforation; a removable colurnn-cap having perforated ears; and a part passing through the ears and said lateral perforation and fastening the cap to the column.

G. The combination in a truck end, of a column 3 a bent bar or tie; a cap having ears connected by means of a part formed to fit the outside of the bend,y in the bar or tie, and means for detachably fastening the cap to the column.

7. The combination ina truck end of a pair of columns; a pair of caps made integral and formed to fit the outside of the bends in a bar or tie; and means for detachably fastening each cap to the adjacent column.

S. The combination of a pair of columns, an arch-bar; a pair of removable caps formed to fit the outside of the bends in the bar; and a pair of column-bolts passing through the arch-bar and each passing through one of said caps.

9. The combinationof a pair of columns, each having a pair of outwardly-projecting perforated ears; a bent bar; a pair of caps formed to lit the bends in the bar; and each provided with a pair of perforated ears and means for fastening said caps to the columnears, which pass through the column and cap ears, substantially as described.

l0. The combination of a pair of columns; an arch-bar, an inverted-arch bar, a tie-bar, a pair of caps II formed integral; a pair of 4caps I, and means for securing the caps to the columns substantially as described.
